The primary causes of blurry canvas drawings include − Device Pixel Ratio − Different devices have varying pixel densities, causing the browser to scale canvas content. Half-pixel positioning − Drawing on fractional pixel coordinates forces the browser to use anti-aliasing. Canvas size mismatch − When canvas display size differs from its actual resolution. ...
